Figure 33 is a'perspective view of the gear system which actuates thevarious parts of the machine.

Describing the machine generally and referring first to Figures 1-3, thedevice comprises a gate member 2 having a plurality of horizontal gates4, as best seen in Figure 3. The gates are aligned with a plurality ofbelt conveyors 5 forming part of a mechanism (not shown) for performingan operation such as printing on tabs or tickets which are conveyed bythe conveyors to the respective gates t.

The tabs are raked from the gates 4 by a raker assembly, generallydesignated 6 (Figures 1 and 2) which moves the tabs onto sliding tabcarriers 8 forming part of a carrier assembly hereinafter described indetail. The tabs are conveyed by the carriers 8 as the latter are movedto their closed or contracted position at the longitudinal center lineof the machine, as best seen in Figure 3.

The tabs are then picked up from the carriers by a head it (Figure 2)which carries the tabs to a backing support wheel 12 wiping the tabsacross glue fingers M which are actuated, as hereinafter described, tointercept the path of the tabs as they are carried toward the wheel Thecarrier head It then presses the tabs against the wheel which, in theillustrated era-- bodiment of the invention, carries a flexible backingelement such as a piece of cardboard, to which the tabs are glued orpasted.

The tabs are then held against the backing element by a clamp orretainer plate I8 until the carrier head moves on the return phase orstroke of its cycle to the carrier 8 which have received a new set oftabs, as heretofore described.

The wheel :2 is rotated, as hereinafter described in detail, to a newposition for each ad- Vance stroke of the carrier head is so that thetabs overlap each other in the illustrated em bodiment of the invention,as best seen in Figure 1. As will be understood from the detaileddiscussion of the wheel-actuating mechanism, the movement of the wheelmay be adjusted to produce any desired arrangement or pattern of thetabs on the backing element carried by the wheel.

Describing the machine in detail and referring first to the backingsupport wheel and associated actuating mechanism, the wheel comprises ahub 22 (Figures 3 and 4) rotatably mounted on a shaft or axle 2 carriedby the frame 26 of the machine. The wheel is rotated on the shafti l ina clockwise direction, as seen in Figures 1 and 2, by a ratchetmechanism 28, hereinafter described in detail. The wheel is providedwith pairs of clamp bars 39 resiliently urged against the outerperimeter of the wheel by spring and bolt assemblies 3!, as best seen inFigures 2 and 4, each bar having an arm 32 with which to rock the baragainst the resistance of the associated springs for lifting an edge ofthe bar to receive a backing element to which the tabs or tickets are tobe affixed, as hereinafter described.

The wheel-actuating ratchet mechanism 23 comprises an annular ratchetplate 36 fixed to the wheel [2 and having teeth 3? (Figures 1 and 2) forengagement by a pawl 38, as best seen in Figure 4. The pawl is mountedin a bracket 35 keyed to the shaft 24 and containing an adjustablespring 39 (Figures 2 and 4) bearing against a spring seat 4| on the pawl38 to urge the latter into engagement with the teeth 37 of the plate 36.The pawl 38 carries at its lower extremity a roller 46 engageable with acam 42 keyed to a collar 44 which is rotatably mounted on the shaft 24.inafter described, to intermittently disengage the pawl 38 with respectto the ratchet plate 36.

The shaft 24 is also keyed to a lever 48 carrying a roller 52 engageablewith a cam 52 operated by a gear system hereinafter described. As bestseen in Figure l, the roller 59 is adjustably mounted by a bolt 56 andset screws 5'! within a slot in the lever to raise and lower the roller58, thereby accommodating adjustment of the extent to which the lever 48is rotated by the cam 52. In this manner the rotational increment of thewheel H2 at each actuation of the lever 48 may be adjusted.

It may be noted, as hereinafter discussed in connection with theoperation of the machine, that the pawl 38 and the lever 48 are actuatedso that the pawl 38 is raised by its associated cam 42 as the lever 68is lowered by its associated cam 52 to the lowest position accommodatedby a rotatable stop plate 60 engageable with a stop pin 62 carried bythe lever '58 adjacent its free extremity. The lever is connected to atension spring 64, the lower extremity of which is secured to the frame26, said spring being operable to rotate the lever 8 counterclock ise ordownwardly, as seen in Figures 1 and 2, into engagement with the plate60 when the lever is released from its raised position by the cam 52.Thus as the pawl 38 is raised, the lever 48 is urged downwardly orcounterclockwise by the spring 64 to move the pawl counterclockwise to aposition whereat a new tooth on the ratchet plate 36 is engaged by thepawl as the latter is dropped or released by its associated cam 42',whereupon the lever 38 is raised or moved clockwise by the cam 52, andthe wheel I2 is rotated clockwise to a The cam is actuated, as herenewposition dependent upon the adjustment of theroller B.Counterclockwisemovement of the wheel isjprevented bya brake shoe 66(Figure 2) pivoted at 63 to the frame 26 and urged by a spring inagainst the outer perimeter of the wheel I2 at the flanged edge 12thereof.

It may be noted that the stop plate 60 predetermines the extent of thecounterclockwise movement or drop of thelever 4-8. In the arrangementshown, the plate 6!) .is formed with two radial slots I4 and I6, theslotM being relati-vely shallow and being arranged to register with the pin'62, as each relatively small untoothed segment I8 (Figure 2 of the.ratchet plate 3.6 is inposition to be engaged by the'jpawl 38. Thus thelever 48 is rotated counterclockwise by the spring 64 to the extentaccommodated :by the slot 14, thereby moving the pawl across the spaceI8 into position to engage theinext tooth on the.

plate 36. This provides a small space between the rows of tabs which arefixed to the backing, as hereinafter described. 'The relatively deepslot I6 of thestop plate 60 is adapted to register with the pin 62 asthe pawl reaches each "relatively large 'untoothed segment 19. oftheratchet plate '36. Thus, as theilever '48 is rotated clockwise fromthe slot 16, the wheel I2 is rotated clockwisein a relativelygreat-increment, thereby moving a new backin'g element on the wheel intoposition for the securement 'of tabs thereto.

Thus it will be understood that by substituting .stopplates 60 withradial slots of various depths and ratchet plate 79 suitably toothed,and by adjusting the roller 50, various desired increments of rotationof the wheel l2 may be effected. If desired, a continuously toothedratchet plate 19 may be utilizedso that only the stop plate 60 need bechanged, to adjust actuation of the wheel. In the illustratedembodiment, the diameter of the plateBD is such tha't the pawl 38 ismoved upon lowering of the lever "48 "to a position one toothcounterclockwise from the vertical position of the pawl 38, as shown inFigure 2, except when one of the slots 14 or it is registered with thepin 62. This produces '"a close spacing of the tabs which are thusarranged in overlapping rows on the backing, as seen in Figure 1, aslight spacing of "the tabs at a point approximately centrally'of thebacking being produced, as above described,;when the pin 62 isregistered with the slot 14 of the stop plate 6i).

Referring now to Figures 6-9 inclusive, the carrier assembly is shown indetail, said assembly comprising thebefore-mentioned carriers 8 whichare slidably supported on a pair of frame-mounted rods 80. Each carriercomprises a top suction surface 82 adapted to receive and retain a tab,as hereinafter described, said surface being offset as at 8 4 to fitbeneath the gate member 2, as best seen in Figures 3 and 11, so that thetabs may be raked from the gates 4 onto the surfaces 82, as hereinafterdescribed. One of the inner carriers 8 is shown in detail in Figure 8and comprises a suction port 86 connected to a pair of suction ports 90at the'surface 82 of the carrier. "The carrier 8 also comprises apair oftransverse openings 92 to accommodate the before-mentionedrods 80 and isprovided with a depending perforated lug 94 for connection to a link 95,as best seen in Figure '7. One of the outer carriers 8 is shown inFigure9, the parts thereofbeing substantially the same as those of the innercarrier shown in Figure 8 and bein identified by corresponding .numeralsexcept for the provision of a relatively wide shoulder or ledge 95 atthe outer side thereof, as may also be noted in the rear view of Figure6.

The lug 94 of each inner carrier is connected by a link 96 to a leverQ8, and the lug 9 1 of each outer carrier is connected by a link I00 toa lever I02. It may be noted that each link 98 extends past the adjacentouter carrier 8 for connection to an inner carrier. Each pair of levers98 and I62 are pivotally interconnected by a bolt I53 connected to thelever 98 adjacent its .lower extremity and having a square head I it(Figure 6) received within a complementary slot or opening in the bottomof the lever I82, and the levers 98 and I02 of each pair are fulcrumedasat I06 and I 08 respectively to a frame-mounted bracket H0. The lever98 carries a roller H2 at its lower extremity for engagement with a camI14 mounted on a shaft IE6 (Figure 6.) wnichis' the main cam shaft ofthe machine. As shown in Figure 6, the corresponding levers I62 areconnected by a tension spring M5 to urge the levers and the carriers 8to the closed position shown in the left half of Figure 6 after therollers 2 have been released by the cams H4. The right half of Figure 6shows the levers and the associated carriers 8 in their open position towhich they are moved by the associated cams H4 against the resistance ofthe spring H5.

It may be noted that the levers 98 and I02 of each pair are fulcrumed atdifferent points on the bracket IIU so that the levers I62 which actuatethe outer carriers 8 move through greater arcs than the levers 98 whichactuate the inner carriers 8 inasmuch as the outer carriers move througha distance approximately twice as great as that through which the innercarriersmove during the expansion and contraction phases :of

the carrier assembly cycle. If desired, another spring E E5 may beconnected between the corresponding levers '93 to increase the resilientforce urging the carriers 8 to their closed position after the rollers!2 have moved to their released position, as shown at the left of Figure6.

It maybe noted, as best seen in Figures 6 and 7, that the port of eachcarrier 8 is connected to a flexible vacuum tube I H, the tubes i llbeing connected to a vacuum pipe or line H9 which is connected toassociated valve means serving .a purpose hereinafter described.

Referring now to Figures 10-15 and 22 which show the raker assembly 6 indetail, it will'be seen that each raker, one of which is illustrated indetail in Figure 15, has an opening I22 extending transverselytherethrough for the reception of a rotor rod I24, as best seen inFigure 10. The raker is fixed to the rod 5.24 as by a set screw (notshown) threaded into an opening I26 in-the top of the raker I20. Theraker is provided on its lower rear surface with a flange or ledge I28(Figure '15 adapted to engage a complementary shoulder of a tab I32(Figure 11).. conveyed to the gate member 2, as above noted, by aconveyor belt 5 passing around a roller I36 and between a pair oftightener rollers l38=supported by a frame-mounted shaft Mil forclockwise rotation thereon as seen in Figure 11 to tighten the belt 5. Aknurled idler wheel I42 is provided toride on each belt 5 to guide thetabs carried thereby into the associated gate 4, said wheels M2 beingrotatably mounted on a shaft Id l, the ends of which are bent or flangedrear-.

wardly as at I 46, each end beingjournaled in a The tab is 7 bearingblock I48 mounted on a bracket forming a part of the frame 26.

As each tab is deposited within the associated gate 4, it is removedtherefrom by one of the rakers I 28 which is actuated into engagementwith the tab, as shown in Figure 11 by a lever I52 (Figures 18, 13 and14) fulcrumed at I54 to the frame 26 and urged by a tension spring I55into engagement with an actuating cam I55 mounted on the main cam shaftH5. The lever I52 is pivoted to a link I58 which is in turn pivoted to alever I68 keyed to the rotor rod I24 for rotation thereof. It may benoted that each end of the rod I24 is journaled in a bearing IEI (Figure11) which is slidably mounted in a slide bracket I83 supported by aframe-mounted block I65 which also supports one end of the gate member2.

Thus as the lever i52 is rotated in a counterclockwise direction by thecam I 56 which engages a roller I67 mounted on the lower end of thelever I52, the rod I24 and the associated rakers I28 are rotated fromthe release or raised position thereof to the lowered or tab-engagingposition shown in Figures 11 and 13. While the rakers are lowered therotor rod I24 is urged for-' wardly on its advance stroke by a pair ofarms I52 connected thereto by links I69 and keyed to a rotatable shaftI54 which is supported by the frame, said shaft being connected to anactuating spring I65 (Figures and 13) by a lever I68 keyed to the shaftI 64 and connected to a rod I18 sleeved within the spring I56 andcarrying a seat I72 engaging the upper end thereof. The lower end of thespring I66 is supported by a frame-mounted spring seat I I4 (Figures 10and 22). The spring I68 is operable to actuate the arms I62 and theshaft I64 by rotating the lever I 68 and the shaft I54 in acounterclockwise direction, as seen in Figures 11, 13 and 14, whereuponthe tabs I are urged by the rakers I28 on their advance stroke, shown insolid iines in Figure 14, thereby moving the tabs onto the carriers 8which are at this time registered with the gates 4. The rakers I26 arethen raised to their release position shown in dotted lines in Figure14, as the roller I8! on the lever I52 rides downwardly to the smallestradius of the cam I55, as shown in dotted lines in Figure 14. The rakersI20 are then moved on the return stroke or phase of their cycle to theposition shown in Figure 13 by a rod I18 (Figures 13 and 14) pivoted at8 to a lever I88 keyed to the shaft I64, said rod H6 having a fork I82(Figures 13 and 22) engaging the cam shaft I I6 and carrying a rollerI84 engaged with a cam H35 mounted on said shaft for actuation of therod H6 to move the rakers on their return stroke.

Referring now to Figures 16-21 which show in detail the carrier orsucker head If and its associated actuating mechanism, the assemblycomprises a bracket I88, shown in detail in Figures 16 and 18, andhaving a transverse opening I98 for the reception of an associated shaftI92 fixed thereto. The bracket also comprises a pair of cylindrical lugs53 at opposite sides thereof with longitudinal pin openings I 54 for apurpose hereinafter described. The bracket is slotted at I95 for thereception of a roller 95 which is mounted between a pair of blocks I98and 29:} havin a pin and socket connection at 282 (Figure 16) andfixedly connected to a pair of rods 204 extending through the openingsI54 in the bracket I88. Each pin is fixed to the sucker head I!) whichis shown in detail in Figures 16 and 19, and a spring 288 is sleevedover each pin under compression between the sucker head and theassociated bracket lug I93 to urge the head to its extended position, asshown in Figure 16, wherein the head is engaged with the carriers 8 tolift the associated tabs therefrom.

The sucker head has four suction faces 2 I0 (Figure 19) with suctionports 212 therein communicating with a passage 214 connected to aflexible vacuum line 2 I 6.

In operation of the sucker head, it is actuated on its advance stroke tothe wheel I2 by a lever 2I8 keyed to the shaft I92 and pivotallyconnected to an actuator rod 220, the lower end of which is providedwith a fork 222 embracing the cam shaft H5 and carrying a roller 224engaged with a cam 225 on the cam shaft. The rod 220 is connected to aspring 221', the lower end of which is mounted on the frame 26 for urginthe sucker head to its return position when the roller 224 engages thesmallest radius of the cam 226. In Figure 1'7, the cam 228 and theroller 224 are illustrated in solid lines in the lowest position of theroller at which the sucker head in, as shown in solid lines, is at theend of its return stroke in engagement with the carriers 8 which are atthis time in their closed position, as shown in Figure 16. The cam 228,roller 224 and sucker head II) are shown in dotted lines in Figure 1'7in the position at which the sucker head I6 at the end of its advancestroke engages the wheel I2 to press the tab I32 thereagainst.

Figures 1'7, 20 and 21 show the actuating mechanism for extending andretracting the sucker head with respect to the bracket I93, saidmechanism comprising a finger 2253 (Figure 1'?) engaging the roller I96and fixed to a rotatable frame-mounted shaft 238 which is fixedlyconnected to a lever 232 (Figures 20 and 21). The lever 232 is pivotedto an actuator rod 234 carrying a roller 238 adjacent its lowerextremity which is provided with a fork 239 embracing the cam shaft lit.The roller 238 is engaged with a cam 248 mounted on the shaft I I6. Thiscam has two flat faces 242 and 244, the face 242 being closest Thus asthe to the axis of the cam shaft iIG. sucker head l8 reaches its returnposition shown in solid lines in Figure 1'7, the face 244 engages theroller 238 to accommodate counterclockwise rotation of the lever 232 bya spring 246 connected thereto and to the frame 25. This action lowersthe finger 228 to extend the sucker head to a point slightly above thecarriers thereby lifting the associated tickets therefrom, as hereinafter more fully described in connection with the vacuum valvesconnecting the sucker head and carriers to associated vacuum lines. Whenthe sucker head I8 reaches its advance position adjacent the wheel I2,the face 242 of the cam 240 engages the roller 238, therebyaccommodating lowering of the finger 228 to afford full extensionof thesucker head by the springs 208 which press the head and the associatedtabs firmly against the wheel I2, as shown in dotted lines in Figure 17.It may be noted as shown in dotted lines in Figure 20 that as the suckerhead moves to and from its advance and return positions the roller 238rides on the arcuate portions of the cam 248 intermediate the faces 252and 244, whereby the finger 228 is raised to lift the sucker head to itsretracted position relative to the bracket against the resistance of thesprings 258.

As the, sucker head reaches its advance and extended position the tabscarried to the wheel I2 are held thereagainst by the clamp plate I8which is supported at one end thereof by a pintle 252 (Figure 3)journalled in a bracket 250'
